Method and system for use of intelligent network processing to prematurely wake up a terminating mobile station

A system comprising:

• a wireless communication device;
• a switch;
• a service control function;
• and
• a communication server,
• wherein the wireless communication device is arranged (i) to receive a user request to initiate a packet-based real-time media session with at least one target party and (ii) to responsively send to the switch via an air interface access channel a call origination message that carries a session-initiation feature code and a target code indicative of the at least one target party,
• wherein, upon receipt of the call origination message, the switch is arranged to detect the session-initiation feature code as an intelligent-network trigger and to responsively send a first message to the service control function, providing the service control function with at least the target code and an identification of the wireless communication device,
• wherein the service control function is arranged to receive the first message, pursuant to service logic, to send a second message to the communication server, providing the communication server with at least the target code and an identification of the wireless communication device, and
• the communication server is arranged to receive the second message and to responsively invite the wireless communication device and the at least one target party to participate in the packet-based real-time media session via the communication server.
